Abstract (en)

An improved method for preparing monolith adsorbents and activating the adsorbents therein is disclosed. A mixture of lower (decomposition) temperature and higher (decomposition) temperature binders is used in fabricating the paper used to form the monolith structure. The finished monolith structure is heated to a temperature sufficient to remove the lower temperature binder while leaving the higher temperature binder to maintain integrity in the monolith.
